Imago UV Hardware Configuration

The Imago platform is able to handle any kind of imagery. Ultra Violet fluorescence can be assessed using off the shelf hardware and the imago software.  This is particularly useful in deposits with carbonates or other fluorescing minerals. 

We have incorporated the ability to control light sources and camera settings in Imago Capture X so you can capture visible and UV Light images seamlessly. Here is an example of its usage: 

Imago Capture X will switch between white and UV light, and also will adjust camera settings automatically when you select Wet or UV respectively making the process very fast and simple. Images will be loaded into Imago's Web Portal.

Once in the portal, you will be able to turn on and display visible and UV light images, plus all the imagery of your project. 

Geological Importance

Luminescence alteration is produced along the flow path of mineralizing fluids. Fluorescent (Mn-rich) veins are an indication of proximity to the ore-zone.

These fluorescent veins may not be visible or distinguishable under visible light.

By using UV light veins can be picked up easily.

Hardware Requirements

Imago connects to an Aviosys Power Switch 9258 to control the power outlets via a LAN connection.  The power switch needs to be configured to the following static IP: 169.254.42.168 using the Aviosys configuration tool available for download from their website or by direct web configuration. The default IP for each Aviosys model is different so you may need to refer to the manual for that specific model. The manual also explains how to do this. The Aviosys configuration tool available for download from their website.  It can also be accessed via a web browser by calling the default IP given to the device while on a network (user: admin / password: 12345678). Below is a screen capture of the app when it is already configured to the address the Imago will read.

The power switch needs to be configured to the following static IP: 169.254.42.168.

Imago CaptureX will communicate to the device on IP above therefore the LAN network adapter used needs to either dynamically select the corresponding range or must be manually set to: 169.254.42.* (e.g. 169.254.42.141) in the windows network adapter settings.

To test the box is correctly responding you can use the following URL on your browser: http://169.254.42.168/set.cmd?user=admin&pass=12345678&cmd=getpower

The UV Systems Triple Bright 3 light is recommended in short wave.  Verify if the minerals you are interested in fluoresce in short wave or long wave UV and adjust your light accordingly. This light is designed for constant cycling and has two power cords.  Please connect the background light cord to a wall outlet and the second cord to the power switch.

Imago Capture will need to be configured with a specific profile so camera parameters are fixed for each type of light.  Following is a list of possible parameters that can be used: Camera Controls.txt  These need to be added to a profile like such: UV_profile.json

This is how a setup could look like. A dark room (or box in this case) with a DSRL camera on top of the sample in a fixed position, white light lamp, and UV light lamp. All that is needed to operate the workflow is a laptop with Imago Capture X installed.
